About Long Island Exterior Co.
Long Island Exterior Co. was founded in 2015 with a simple mission: provide Long Island homeowners with honest, high-quality exterior renovation services at fair prices. Based in Hempstead, NY, we serve all of Nassau County and Suffolk County — over 200 communities across Long Island.
What started as a small roofing crew has grown into a full-service exterior company handling roof replacements, siding installations, and chimney services. But our core values haven't changed: every project gets the same meticulous attention, whether it's a Cape Cod in Levittown or a waterfront estate in the Hamptons.
We are proud to be one of only 1% of roofing contractors nationwide to hold GAF Master Elite® certification. This means our installations meet the highest industry standards and qualify for the strongest manufacturer warranties available, including GAF's Golden Pledge® lifetime coverage.
Our Commitment
- Local expertise: We understand Long Island's unique climate — nor'easters, salt air, ice dams, and the specific building codes across every town and village.
- No subcontractors: Every project is completed by our trained, in-house crew. Period.
- Transparent pricing: Detailed, itemized estimates with no hidden fees or surprise charges.
- Community first: We live and work on Long Island. Our reputation is built one neighbor at a time.
